Organic carbon from Mars, but not biological

(Phys.org) -- Molecules containing large chains of carbon and hydrogen--the building blocks of all life on Earth--have been the targets of missions to Mars from Viking to the present day. While these molecules have previously ...

Pinpointing catalytic reactions on carbon nanotubes

(PhysOrg.com) -- Among their many other interesting properties, carbon nanotubes have been found to act as catalysts for some important chemical reactions, including some that could be used to make cleaner fuels. But many ...

New molecules to modulate gene expression

The correct functioning of cells relies heavily on the ability to finely control gene expression, a complex process by which the information contained in DNA is copied into RNA to eventually give rise to all the proteins ...

Implantable batteries can run on the body's own oxygen

From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and to dampen pain. But batteries eventually run low and require invasive surgeries to replace.
